STEFAN HALPER'S TARGETS IN TRUMPWORLD

CIA-linked Cambridge professor Stefan Halper tried to get close to at least three Donald Trump advisers in 2016 and 2017, reportedly to learn for the FBI whether they were links between the Trump campaign and Moscow.

Here's a look at some of the key figures in the latest drama in Trump-world:

Carter Page

Carter Page was a Trump advisor that drew immediate interest of investigators due to his longstanding Russia ties. The New York Times reported that a government informant met with him several times during the campaign.

He is mentioned repeatedly in the Steele dossier, and was the subject of a Foreign Intelligence Surveillance Court warrant that authorized monitoring of his activities.

George Papadopoulos

Papadopoulos was one of just a handful of early foreign policy advisors identified by President Trump at the start of his campaign. His boozy chat with the top Australian diplomat in London helped kick off the Russia probe. Halper met with him several times during the campaign.

Halper arranged for him to get paid $3,000 for a policy paper on energy issues, and emailed him about the status of the 'collusion' investigation

Sam Clovis

Halper met with Clovis offering to assist the campaign with his foreign policy expertise. Their conversations over coffee in northern Virginia focused on China, according to Clovis' lawyer. He served as co-chair of Trump's campaign and according to court records recruited Papadopoulos, a young aide without a long resume, to join the campaign.

Sam Clovis ran for office in Iowa and hosted a conservative radio show, then co-chaired Donald Trump's campaign. He recruited George Papadopoulos to join the effort
